Your "hardware" will use it.
Here's a cut-n-paste:
---BEGIN---
Significant chunks of address space below 4GB (the highest address
accessible via 32-bit) get reserved for use by system hardware:
=95 BIOS =96 including ACPI and legacy video support
=95 PCI bus including bridges etc.
=95 PCI Express support will reserve at least 256MB, up to 768MB =
depending
on graphics card installed memory
What this means is a typical system may see between ~256MB and 1GB of
address space below 4GB reserved for hardware use that the OS cannot =
access.
Intel chipset specs are pretty good at explaining what address ranges =
gets
reserved by default and in some cases call out that 1.5GB is always =
reserved
and thus inaccessible to Windows.
---END---
You can read the whole thing here:

lem
.aspx
32-bit OS is limited to 4GB addressable space. 32-bit Windows CAN access =
4GB
of addressable space, though will be prevented from doing so only =
because it
won't see it. If you read that article, that was the best I could find =
in
pretty much plain English. A lot more other MUCH MORE TECHNICAL articles
were available, though this one seemed to be the best read.
